BRAIN RETRACTOR FIXING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a brain retractor fixing device that facilitates moving to a place intended by a user, and may not be buckled in a base part of a flexible arm in order to be stably fixed in the place intended.SOLUTION: A brain retractor fixing device is constituted of a flexible arm to be fixed using a frictional force of a free lock connection part by tightening and loosening the wire inserted in a large number of free locks, and is adjusted so that a frictional force between the free locks becomes smaller in the tip part and becomes larger in the base part by changing the diameter of the free locks so that the force to start buckling becomes constant in each connection point of the free locks.SELECTED DRAWING: Figure 1
